Remediation & Strengthening

Sterling specializes in remedial design for deteriorated bridges and structures, with a deep and broad pedigree in "renovating" aging infrastructure rather than replacement. Our remediation approach prioritizes targeted intervention over wholesale reconstruction — extending asset service life while minimising capital expenditure, network disruption, and environmental impact.

The key advantage of Sterling's integrated model is the direct link between condition assessment and remediation design scope. In fragmented delivery models, defects identified in inspections are handed off to separate design consultants, introducing delays, scope misinterpretation, and redundant site visits. By having Sterling deliver remedial design in-house, the engineers who inspect the asset also define the repair scope, ensuring design intent matches actual defect conditions and risk profiles without handover inefficiencies.

Sterling has delivered remediation designs for major rail infrastructure including the Swan Street mezzanine repairs for Metro Trains Melbourne, ARTC bridge strengthening programs, V/Line structure renewals, and Parks Victoria timber bridge repairs. Our designs account for construction constraints (live rail operations, traffic management, access limitations), material availability, and maintenance crew capabilities, ensuring remediation solutions are practical, cost-effective, and deliverable within operational constraints.
